The framework of the BugDorm-6 insect rearing cages are made of solid aluminum pipes. These cages, sizes from 60 cm to 2 meters, are tall enough to place large potted plants inside or serve as a walk-in enclosure. The BugDorm-6E insect rearing cages use very dense fabric with a mesh aperture of only 160µm, which will effectively keep minute insects like Thrips from entering or escaping the cage.
